TO ALL WHOM IT MAY CONCERN: I

Be it known that I, ABRAM REESE, of the city of Pittsburg, in the county of Allegheny, and State of Pennsylvania, have invented a new and useful Improvement in Rolls for Rolling Iron of varying width and thickness; and I do hereby declare the following to be a full, clear, and exact description thereof, reference being bad to the accompanying drawings, making a part of this specification, in which i I Figure is a side elevation of my improved rolls.

Figure2 is a horizontal vertical'section of one end of my improved rolls, and more particularly illustrating the characteristic feature of my invention, and V Figure 3 is an end view of the rolls. v

Likclettcrs of reference designate like parts.

The object of my invention is to roll metallic bars, or a suceessionbfmetallic blank-s of variable width and thickness, from which bars or blanks to cut and bend horse-shoes, or other articles capable of heingmade of such material and by such process; and the nature of it consistsin the construction and arrangement on one oi a pair of cylindrical rolls of one or more movable collars, which form one or both sides of the groove or die in which such bars or blanks are to be rolled, such collar or collars being susceptible of motion laterally or lengthways of the roll, and furnished with a spring or springs, either fixed or adjustable, for the purpose of increasing the width of the groove as the collar is pressed outwards. v

To enable others skilled in the art to make and use myinvention, Iwill proceed to describe its construction and mode of operation. I g i a and a are two cylindrical metallic rolls, of the ordinary construction, and grooved and flanged in the ordinary way, except as hereinai'ter to be described. In the grooves c 1, and under the corresponding flanges c c, I reduce the iron to bars of any desired breadth and thickness. As shown in the drawings, fig. 2, the roll a is at one end reduced in diameter, or shouldered, and a collar, 0?, fitted thereon, between which and the shoulder or flange 2' is the" groove s. The bottom of the groove sis madewith a print, e, of any variable shape which it may be desirable to give to either face. of the bar or series of blanks to be rolled. The roll a has, onq'ts outer face, and opposite the groove 8, one or more projections or creases, c, which give shape to the other face of the bar. As it is often desirable to increas'c' the width of a bar at thesame time that its thickness is lessened, and vice verse, I provide for such variation by adjusting on the cylindrical roll a, as already stated, a movable springcollar, d, which forms one side of the groove e. This collard is movable laterally or lengthways of the roll, so as to increase the width of the groove 8. When the bar, under the effect of the printc or projectionse, or both,-

is reduced in thickness, the increase of lateral pressurecaused thereby forces the collard out, and increases the width of the groove 8. When such increase of lateral pressure is removed, the collar d is moved. back, so as to restore the former width of the groove s,vand consequently the Width of the bar or blank whichis beingrolled,

by a spring, 71., which, in the form shown in tlie drawing, is so bent as to be readily and Securely attached to the roll at its centre, and with its ends operating against the collar (Z. But the shape of the spring is not material, nor its mode of attachment. It may be of any 'known form, curved, coiled, spiral, elliptic, or of other regular or irregular shape, and so'attached asto work against the collar d in any convenient or known manner. It"

desirable, a slot may heimade through the roll a, and a spring inserted therein to work the collar. Either or both sides of the groove s may be made with a collar, operated substantially in the same way. I also, some times, rim out either or both such collars, so that they may project over and cover, when desirable, apart or the whole of the print 'e. Bythe use of slots, and various forins of springs, I adjust and operate such collars (Z, not only on the ends of such rolls, but also at any point or points intermediate between such ends. Keys 0, of theusual or any known mode of construction, I also use to prevent the sliding of the collar (Z on its roll a, as the latter revolves, and at the same time oil er no material resistance to its free lateral motion. The spring It may he made adjustable, if so desired, by a screw, 0:, or by other equivalent well-known means, in which way the pressure of the collar d against the-bar passing through the rolls may easily be regulated.

The machine shown in the drawings is particularly adapted to rolling horse-shoe blanks, the print e being of the proper shape to flare or bev el the inner'edge of the upper face of the shoe, and the creasers e being properly shaped and arranged for creasing the lower face of the shoe; andsince the depth of the print a, and

consequently the bevel or flare of the shoe-blan'k, is greatest attthe middle of the blank, or, in other words, at

the toe of the shoe, the operation of the collar 01 will, as above shown, be such as to secure in the blank the required increase of width at the same point. ,But I apply .this mode (if rolling to forming bal s er blanks of other shapes, and for the various puvposesrequirecl in commerce and trade, and apply it to rolling iron, steel, or other metal capable of being shaped in that way.

What I claim as my invention, and desire tosecure by Letters Patent, is- Y The die, formed by the face of the roll a, the collar e, and the spring-collar cl, substantially as and for the purposes hereinbefore described. v

In testimony whereof I, the said ABRAM REEsE, have hereunto set my hand.
